Do this with both spars if the front spar top or bottom is sloped.


good luck with this, John
John,

Looking forward to trying this ASAP!

From my location here, I cannot see my own photobucket link (filtered) but, I recall last night thinking that I did not like how the bottom edge was lining up toward the trailing edge. That favored the rotation as noted by Pete.

Still, first off I will reconfirm the Spar section (both) and include those edges in the curve geometry as you suggest.

I agree fully with Sid,...it has to fit and fit correctly! I took a quick peek at the Strutter in France and although a bad camera angle, this photo confirms several points.

1) Both cut-outs clear the cap strips

2) The "reversing" curve along the bottom near the aft spar was bothering me. I see it here in their Strutter,...whew!

3) Both the Pup and the Baby share a similar aft spar geometry which differs from the Strutter.







Thanks again!
